Abstract
THE eye shows a supernormal sensitivity to an electric stimulus after exposure to light. This property was utilized by Motokawa1,2 for analysing physiological processes of colour vision. In the present experiment similar measurements were carried out with a test-patch of reduced visual angle (2 minutes of arc), instead of a greater one of 2 degrees used in Motokawa's experiments. The apparatus for micro-stimulation was a reducing lens system similar to that devised by Hartridge3.
